Brazen swindlers. My bag fit easily into the carry-on size box. I bought a ticket with hand luggage. But they refused to put me on the plane until I paid for my hand luggage as baggage. Why did they create the measuring box? If it doesn't make sense. I showed a screenshot from their corporate website, where the dimensions of hand luggage were indicated. But the company employees didn’t care about the site.

Not the greatest of experiences - paid upgrades not honored and check in consultants were not particularly helpful and/or were very inexperienced. Furthermore, the customer service was lacking and will result in refunds only being processed (or at least I've been told) within 21 days of travel. As a result, I have decided not to book with United Airlines in the future.

Flying from Heathrow to San Francisco where I normally fly virgin who i would recommend, United Airlines gave me Terrible service, no screen for whole flight and no compensation , checking in was a million questions, staff weren’t at all sorry would never use again,😡😡😡

The most disgusting airlines have been created on this planet. Delayed flights no food, extremely rude personal horrible customer service.
I wish you to close your doors and bankrupt in the shortest period time as possible from the bottom of my heart

This was by far the worst trip I have experienced with an airline on my life. They have constant delays and do not explain what for. It is the worst airline. Spirit airlines seems like heven comparatively. Though the flight attendance were kind the delays cost over 2:00 of waisted time! I will never fly this airline willingly again!
